Abstract

A compact and portable moire interferometer used to determine surface deformations of an object. The improved interferometer is comprised of a laser beam, optical and fiber optics devices coupling the beam to one or more evanescent wave splitters, and collimating lenses directing the split beam at one or more specimen gratings. Observation means including film and video cameras may be used to view and record the resultant fringe patterns.

Compact portable diffraction moire interferometer

Patent Deason, V A ; Ward, M B

This patent describes an interferometer for performing the method of diffraction moire. It comprises: a source of a beam of coherent light, coupling means for coupling the beam of coherent light into a polarization maintaining single mode optical fiber; beam splitting means for splitting the beam of coherent light from the optical fiber into at least two beams of mutually coherent light; collimating means, directing the mutually coherent beams at one or more diffraction gratings replicated onto the surface of a work piece; observation means for viewing and measuring interference patterns created by the diffraction of the beams by themore » diffraction gratings.« less
Fiber optic diffraction grating maker

Patent Application Deason, V A ; Ward, M B

A compact and portable diffraction grating maker comprised of a laser beam, optical and fiber optics devices coupling the beam to one or more evanescent beam splitters, and collimating lenses or mirrors directing the split beam at an appropriate photosensitive material. The collimating optics, the output ends of the fiber optic coupler and the photosensitive plate holder are all mounted on an articulated framework so that the angle of intersection of the beams can be altered at will without disturbing the spatial filter, collimation or beam quality, and assuring that the beams will always intersect at the position of themore » plate. 4 figs.« less
